When we exercise we actually shorten our muscles and
increase their mass.

That
is how we raise the buttocks, tuck in our stomach and shape
our arms and legs.

It works out this way because
of our muscles’ physiology.

Inside a muscle cell there are certain proteins responsible for contraction at
the brain’s command. The more contraction commands, the more demanding it gets
for our body… so it reacts by producing more protein within the existing muscle
cells. More protein, more contracting power.

This mechanism works both ways: untrained muscles discard large
amounts of contracting protein because they just don’t need it,
leaving the muscles weak and saggy.

Protein has mass, so when the body produces
more protein within the cells, the muscle as a whole becomes both shorter and more
substantial.

So by regularly exercising your facial
muscles you can prevent muscle loss and maintain a young and vibrant apperance.
